Hi @jbrennerFIT!
Sounds like an exciting call, does this NSF call have any limitations on where people and their organisations are based?
And thanks for sharing the 347 articles you found! In case this helps, there is the Zotero group library on open source hardware maintained by GOSH people, and it would be useful to consolidate the references. This shared library is currently used for the literature review that @unixjazz is leading in this thread.
